Conjunctival cystectomy assisted by pattern scan laser photocoagulation.

BACKGROUND: To introduce a new technique of laser-assisted conjunctival cystectomy using pattern scan laser (PASCAL) photocoagulation.

CASE PRESENTATION: A 50-years-old Asian woman presented with a conjunctival cyst in the left eye. Slit-lamp examination revealed a 5 mm × 2 mm sized freely movable conjunctival cyst. After a 1 mm × 1 mm sized conjunctival opening was made using PASCAL photocoagulation, the cyst was extracted using a non-toothed forceps without rupture. Two weeks later, complete re-epithelialization of the conjunctiva was observed without any complications. No evidence of recurrence was noted over the 6-month follow-up period.

CONCLUSION: Conjunctival cystectomy with the adjunctive use of PASCAL photocoagulation can be an effective and safe treatment method.
